Measure soil water content with the affordably-priced EC-5 Soil Moisture Smart Sensor; this sensor integrates the field-proven ECH2O™ Sensor and a 12-bit A/D, providing ±3% accuracy in typical soil conditions, and ±2% accuracy with soil-specific calibration. The sensor’s two-tine design makes the sensor easy to install. Readings are provided directly in volumetric water content. This sensor's high frequency design gives it a relatively low sensitivity to salinity and textural effects and a wide measurement range.

Measures a 0.3 liter volume of soil

Sensor uses a high-frequency (70 MHz) circuit that provides good accuracy even in high-salinity and sandy soils.

Measurement RangeIn soil: 0 to 0.550(m³/m³)Extended range: -0.401 to 2.574 m³/m³ (full scale)The sensor is capable of providing readings outside the standard volumetric water content range. This is helpful in diagnosing sensor operation and installation. See the Operation section below for more details.

Sensor Operating Temperature: 0° to 50°C (32° to 122°F). While the sensor probe and cable can safely operate at below-freezing temperatures (to -40°C/F) and up to 75°C (167°F), the soil moisture data collected at these extreme temperatures is outside of the sensor's accurate measurement range.

Volume of Influence: 0.3 liter (10.1 oz)

Sensor Frequency: 70 MHz

Bits per Sample: 12

Number of Data Channels: 1 Note: A single smart sensor-compatible HOBO logger can accommodate 15 data channels and up to 100 m (328 ft) of smart sensor cable (the digital communications portion of the sensor cables)
